A comparison of the N(2) fixers in the tall Spartina alterniflora and short S. alterniflora marsh soils was investigated. Zero-order kinetics and first-order kinetics of acetylene reduction were used to describe the activity of the N(2) fixers in marsh soil slurries. It was found that the V(max) values were approximately 10 times greater for the N(2) fixers in the tall Spartina than in the short Spartina marsh when raffinose was used as the energy source. In addition, the (K(s) + S(n)) values… CONTINUE READING
